check_health
Live status, directory-wide or per service (uptime snapshots, consecutive failures).
How to use it
Project documentation lists check_health for the X402 List MCP MCP server. Add the server to your MCP client (Claude Desktop, Cursor, Windsurf and others), then check which tools your installed version makes available. Tool availability can depend on configuration and credentials. A server handshake does not verify this tool’s behavior. See the full listing for setup details.
